I think I agree with Alison. The trees give it a much different feel than I think it will have if you crop them out. I think if you did, it would be much more whimsical, and open to the imagination. :) Love this shot.

No, I like the trees in it, I may be in the minority but I like them as it gives you a reference point to look at the print. It would be much more abstract without the trees, so I guess it depends on what look you are going for. I think the trees add to this print and keep it whimsical. Keep them in.
